I am servicing an Apple G5 Desktop tower computer. The issue is this:
I turn it on and almost immediately the fans kick into full blast. I force shut it down, unplug EVERYTHING, and it powers up, the apple boot sound sounds off and fans run at normal speed.
I then proceed to plug one peripheral one at a time to find the culprit.
WHEN I plug in the monitor and turn on the computer the fans kick into full blast BUT when I power on the apple WITHOUT the monitor plugged in, it powers up and the apple boot sounds sounds off and the fans run normal. I then proceed to plug in the monitor and almost immediately the fans kick into full blast.
So based on that, is the GRAPHICS card going bad? or is it something more serious like the Logic board or CPU?
Thank you in advance for the replies!
